The occurrence of hyperthyroidism after thermal ablation for thyroid papillary carcinoma: a retrospective multicentre observational study.
Observational study in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveIn recent years, the incidence of papillary thyroid carcinoma (PTC) has been rapidly increasing, and thermal ablation techniques are gradually emerging as alternative therapies for PTC. The aim of this study was to comprehensively analyse potential factors leading to hyperthyroidism after thermal ablation treatment for PTC, providing a scientific reference for the prevention of and intervention for hyperthyroidism in such condition in the future.
methodsThrough the analysis of 22 papillary thyroid carcinoma (PTC) patients who received thermal ablation treatment in four different hospitals and later experienced hyperthyroidism during follow-up, we scrutinised their diagnostic and treatment procedures. This comprehensive analysis, in conjunction with pertinent data and reports, sought to delineate optimal approaches for both prevention and treatment.
resultsAmong the PTC patients included in the study, 3 were males and 19 were females, with an average age of 36.05 ± 1.60 years. Thirteen patients underwent radiofrequency ablation treatment, while 9 patients received microwave ablation treatment. Before undergoing treatment, these 22 PTC patients presented no evident abnormalities in thyroid function and did not experience any hyperthyroidism-related symptoms. Additionally, within one week following thermal ablation treatment, thyroid function normalised. During the follow-up period, they subsequently developed hyperthyroidism, accompanied by decreased TSH, along with elevated FT3 and/or FT4. Some patients also presented with clinical symptoms of hyperthyroidism, such as heat intolerance, sweating, hand tremors, palpitations, and other associated signs.
conclusionIn summary, PTC patients who exhibit symptoms of thyroiditis or autoimmune diseases prior to the procedure may be at increased risk of developing hyperthyroidism following thermal ablation treatment.
